Pressure is a very important parameter for combustion diagnostics since pressure is a good indicator of combustion efficiency .As combustion technologies mature, more accurate and less response time pressure diagnosis are needed. Line of sight (LOS) tunable diode laser absorption spectroscopy (TDLAS) provides a fast, nonintrusive, sensitive and reliable solution for quantitative sensing of multiple flow field parameters including gas temperature, components concentration, and mass flux. So far, there is no mature method to measure gas pressure using TDLAS, and it is very important to perfect TDLAS measuring system with the gain of pressure.This paper intends to found a method based on TDLAS for gas pressure measurement. At first, a gas pressure measuring method is presented. Then, an experiment is conducted in a heated static cell to verify this method. A Direct-Absorption-Based Senor which scans H2O transitions near 1.4 μm was used, and this made the measuring system compact, low cost, simple to operate and quick to response. The experiment successfully measured the pressure in several pressure points, and the results agreed well with the data measured by pressure sensor, average difference is 3.1%.
